Suppose you have detected an incoming missile, but you don't know whether or not it's harmless or deadly. According to the experts, if the true proportion (p) of explosives on the missile is greater that 0.9, then it's deadly, in which case it should be shot down. But all you have is the sample proportion ( ) that you have observed (say, via radar) for the incoming missile. - Which of the following is the appropriate Type I error? A) p is truly 0.9, but the p-value from the data suggests p > 0.9. B) p is truly 0.9, but the p-value from the data suggests p < 0.9
